What is the author's style in Mr. Blue by Myles Connolly?

The language and meaning of Mr. Blue reflect the author's intent of drawing a character portrait rather than telling a story with a plot. While there are important events in the book, such as the narrator meeting Mr. Blue, Mr. Blue's disappearance and reappearance, his vocation amongst the poor and his death, the point of the book is to discuss this extraordinary man and his qualities. For instance, Chapter III consists almost entirely of a story the Mr. Blue made up about the last Christian on earth which the narrator repeats because he thought the story represented Mr. Blue's worldview and his understanding of himself in relation to the world.
